Comment 6 for bug 170910

If someone can point me to the part of the code where the
"matrix transform"
apply (where points and handles are multiplied for the
matrix, which can be
scale, rotate, deform) I can try to write down the code on
my own
(need to know where that part of code lies to get confident
with the nodes and
handlers structure), alternatively, if someone knows if
nodes and handlers are
accessible from scripts (effects) I'll try to do this as effect.
